201391· This equation allows the calculation of the product size distribution from a mill once d ij is determined. The calculation of d ij includes the aforementioned S and B functions, which can be determined in a laboratory batch mill. However, these parameters are sensitive to milling conditions such as the mill rotational speed, ball fillingVariables in Ball Mill Operation Paul O. Abbe®,The formula for critical speed is CS = 1/2π √ (g/ (Rr) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (Rr). Dry mills typically operate in the range of 50%70% of CS and most often between 60%65% of CS.
